One viewer. Every drawing. Inside your product.
Use @rasterex/viewer in JavaScript or TypeScript, or embed Canvas with iframe and PostMessage from any HTML-capable frontend.
View package on npmPDF, DWG, DGN, IFC, images, MS Office and 100+ more. One engine, one integration.
Runs on your Windows Server. Drawings never leave your infrastructure.
Your app decides which tools are visible, who can use them, and where the results go.
Targeting a single format? See the PDF SDK, CAD SDK and BIM SDK.
AI-ready. Prompt it, or install it yourself.
@rasterex/viewer is a small, typed, zero-dependency SDK with full docs and runnable examples. Point your AI assistant at it, or install it by hand, and run a project against our backend in minutes. The backend runs as a hosted sandbox for evaluation and proof of concept, so there is nothing to set up on your side to get started.

From proof of concept to production.
When you can see it working and want to move toward your own integration, get in touch. We go into dialogue, build a commercial model around your case, and you install the full backend yourself, on-prem or in your own cloud, with complete control of your data and infrastructure. Rasterex never touches your files or your servers.
